Question

Given below are the electronic configurations

(a) 1s²2s²2p³

(b) 1s²2s²2p⁴

(c) 1s²2s²2p⁵

(d) 1s²2s²2p⁶

The correct order of electronegativity is

(1) a > b > c > d

(2) c > b > a > d

(3) d > c > b > a

(4) c > b > d > a

Answer 1

Correct option is : (2) c > b > a > d

1s²2s²2p³ = N

1s²2s²2p⁴ = O

1s²2s²2p⁵ = F

1s²2s²2p⁶ = Ne

Electronegativity order : F > O > N > Ne
